Development of autoimmune hepatitis in primary biliary cirrhosis.

AIM/BACKGROUND: Primary biliary cirrhosis (PBC) is a chronic cholestatic liver disease of unknown aetiology. Up to 10% of patients with typical features of PBC will have additional features of autoimmune hepatitis (AIH). A subset, however, have no such features but go on to develop a 'sequential' AIH overlap syndrome. Objectives: Describe our experience with eight patients who developed AIH after the diagnosis of PBC was made. METHODS: We reviewed the charts of all PBC patients over a 9-year period (from 1996 to 2005). Only PBC patients with no features of AIH were included. RESULTS: There were 1476 patients with PBC. Of these, eight patients developed features of AIH overlap syndrome based on biochemical and histological parameters. Treatment included prednisone and azathioprine for 24 or more months. The majority of patients remained on ursodeoxycholic acid (UDCA) throughout treatment. Response to therapy was defined by improvement in enzymes, and was rapid for all patients. One patient was able to discontinue treatment with prednisone and azathioprine, while seven have continued on therapy to date. CONCLUSIONS: A 'sequential' overlap syndrome of AIH with PBC can occur. Treatment with prednisone and azathioprine may lead to a rapid improvement in aminotransferase levels.     

中国汉坦病毒H82O5株G2糖蛋白基因的克隆及在真核细胞中的瞬时表达

从感染病毒乳鼠脑组织提取总RNA，采用RT－PCR和分子克隆技术将扩增到的G2糖蛋白基因插入含CMV启动子的pcDNA3.1/His质粒载体中，通过脂质体介导转染COS－7细胞，用SDS－PAGE、Western-blot及IFIA方法分别测定表达产物的相对分子量及特异性。结果证明获得正向插入的G2－pcDNA3.1/His重组表达质粒，表达产物的相对分子量为56ku，与理论预期大小一致，并且可与汉坦病毒H8205株的腹水抗体起特异反应。表明构建的G2－pcDNA3.1/His重组质粒所表达的蛋白为中国汉坦病毒株特有，能在哺乳动物细胞中表达并具有抗原性，重组质粒可应用于汉坦病毒的DNA疫苗研究。

Immunomodulatory activity of Asparagus racemosus on systemic Th1/Th2 immunity: Implications for immunoadjuvant potential

Ethnopharmacological relevance

Roots of Asparagus racemosus Willd (Shatavari in vernacular) are widely used in Ayurveda as Rasayana for immunostimulation, galactogogue as also in treatment of conditions like ulcers and cancer. Various studies have indicated immunomodulatory properties of Shatavari root extracts and formulations.

Aim of the study

To study the effect of standardized Asparagus racemosus root aqueous extract (ARE) on systemic Th1/Th2 immunity of SRBC sensitized animals.

Materials and methods

We used HPTLC to quantify steroidal saponins (Shatavarin IV, Immunoside^®) and flow cytometry to study effects of ARE on Th1/Th2 immunity. SRBC specific antibody titres and DTH responses were also monitored as markers of Th2 and Th1 responses, respectively. We also studied lymphocyte proliferation. Cyclosporin, cyclophosphamide and levamisole were used as controls.

Results

Treatment with ARE (100 mg/(kg b.w. p.o.)) resulted in significant increase of CD3⁺ and CD4/CD8⁺ percentages suggesting its effect on T cell activation. ARE treated animals showed significant up-regulation of Th1 (IL-2, IFN-g) and Th2 (IL-4) cytokines suggesting its mixed Th1/Th2 adjuvant activity. Consistent to this, ARE also showed higher antibody titres and DTH responses. ARE, in combination with LPS, Con A or SRBC, produced a significant proliferation suggesting effect on activated lymphocytes.

Conclusion

The study suggests mixed Th1/Th2 activity of ARE supports its immunoadjuvant potential.
